Bang Pa-In Royal Palace is a summer palace complex featuring buildings in various architectural styles including Thai, Chinese, and European. Located on an island in the Chao Phraya River, it was originally built in the 17th century and later restored by King Rama IV and V. The Chinese-style Wehat Chamrun Palace and Thai pavilion Aisawan Thipya-Art on the lake are particularly stunning. Golf carts can be rented to explore the extensive grounds.
